I have been running the new hobby wing esc with the new lrp x20 6.5 and can't believe how it feels..the esc runs around 90* and the motor around 150*....i tried a Novak havak pro sc with a reedy 6.5 and took it right back out. The Novak was running around 135* & the motor around 165* with no power, it had nothing on top. I even turned up the end bell to 40* and made no difference. The x20 is a big Monster..not booster or no end bell timing..
Here is the link to the esc..
